Here's what you need to know about Asus' latest Android phone, the ZenFone 4 including its release date, price and specifications

The ZenFone 4 is now on sale in the UK along with ZenFone 4 Max

Following the launch of the ZenFone AR a couple of months ago, Asus has announced a new Android phone and called it the ZenFone 4. That's a name Asus has used in the past, which rather confuses things.

When is the ZenFone 4 release date?

The ZenFone 4 is now on sale from Asus' eShop, and you can also buy it from Carphone Warehouse, John Lewis, Amazon, Box and Tesco.

There's a second model the ZenFone 4 Max. The Max refers to a huge 5000mAh battery, not a larger screen. You can see the full specs of both phones below.

The camera also benefits from optical stabilisation on four axis which allows long(ish) exposures of 1/4 sec.

and image processing is handled by a Qualcomm Spectra 160 chip.

The wide-angle camera isn't ultra-wide like LG's recent phones, but it has a 120° field of view which lets you fit a fair bit more in the frame without introducing too much distortion.

There's plenty of flagship-level components including Cat 12 LTE, Bluetooth 5, 802.11ac Wi-Fi, and you get extras missing from the 'Max' version such as USB-C, hi-res audio, stereo speakers, a fingerprint sensor and NFC.

Asus keeps the price down by sticking with a full HD screen rather than quad HD, and there's no waterproofing.

ZenFone 4 Max

Similar in name and design, but very different inside, the Max is intended to offer huge battery life for those on a tighter budget that don't care so much about having the best cameras and fastest processor.

The ZenFone 4 Max can act as a power bank and charge other devices thanks to the included OTG USB cable.

It has a similar dual camera setup to its pricier stablemate, but although the 13Mp main camera has extra resolution, it doesn't have optical stabilisation.
